Introduce a PSCI DT helper function, psci_dt_attach_cpu(), which takes a CPU number as an in-parameter and tries to attach the CPU's struct device to its corresponding PM domain. Let's makes use of dev_pm_domain_attach_by_name(), as it allows us to specify "psci" as the "name" of the PM domain to attach to. Additionally, let's also prepare the attached device to be power managed via runtime PM. Note that, the implementation of the new helper function is in a new separate c-file, which may seems a bit too much at this point. However, subsequent changes that implements the remaining part of the PM domain support for cpuidle-psci, helps to justify this split.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
